Abstract: Methods and systems for performing signal pre-correction of a transmission signal comprising a sequence of symbols using a Pattern Dependent Look-up Table (PDLUT) containing one or more distortion correction values.

Abstract: Disclosed herein include a system and a method of synchronizing a slave device to a signal from a master device based on pulse width analysis. The pulse width analysis is a process to sample the signal at a sampling frequency of the slave device, determine varying pulse widths of the sampled signal, and determine frequency of an embedded master clock signal of the signal based on statistical analysis of the varying pulse widths. Advantageously, performing pulse width analysis allows synchronization of a slave device with the embedded master clock signal in a time and cost efficient manner. In one aspect, determining a frequency of the embedded master clock signal and adjusting an internal clock of the slave device according to the determined frequency is faster and more cost efficient than iteratively adjusting the internal clock based on feedback loop based circuitries.

Abstract: A backward compatible frame reuse mechanism that allows new information to be defined a reused frame without causing any incorrect operation in a legacy receive device. To generate a reused frame, a portion of the frame in the first format is masked with a predetermined masking sequence (PMS) and thereby redefined as new fields in a second format. When a device that supports the reuse scheme receives a frame that possible is a reused frame, the device checks the potentially reused portion according to the first format after de-masking and also checks according to the second format without de-masking. Based on the check results, the device selects a format to resolve the frame. A legacy device receiving the reused frame only checks the reused portion without de-masking, which results in a certain check error and makes the device discard the frame without any harmful operation.
